You removed the bikini top in record time, but as you stared at your chest, you could see something was badly wrong. Your chest looked slightly swollen, and worse, your nipples were slightly enlarged, and had a darker color.
"Melanie! What have you done?!" you ranted, knowing that your chest looked like what it would if you were about to undergo female puberty. "I know what this is. Change me back right.... Damn it, I mean NOW!" Already furious, you watched as your nipples deepened and grew out even more. After they tripled in size, you felt a slight pressure in your chest as two small lumps formed. They didn't stay small; the lumps rapidly expanded almost like a balloon. You were silent as the womanly flesh on your chest became larger than Megan's, but as your breasts grew larger than Mel's, you exploded.
"I'm not a girl! If you won't stop your magic, I'll try it myself" you snapped. Even though Megan's and Mel's attention was directed at your altered body, Mel managed (barely) to keep the book away from you, which in itself was a very bad sign. Looking around your body, you saw that you had lost considerable muscle mass, as well as some height, explaining why you couldn't overpower her. Agility wise, you were outgunned, as your torso was changing. You couldn't move as easily, not used to your expanding hips, or the increasingly obvious hourglass shape of your body. Nor could you handle the strange feeling of extra padding in your rapidly inflating rear as it become heart shaped. Tripping, you landed on your inflated rear, and watched helplessly as your arms and legs changed. All the hair on them instantly fell out as they shifted into a thinner, more feminine looking form. The changes progressed to your hands and feet; they slimmed down as easily as your limbs, and unsurprisingly, your fingernails and toenails grew out slightly before they were coated in a hot pink lacquer. Immediately after your limbs, you felt a tingling feeling in your groin. Sobbing slightly, you watched the slight bulge in your bikini bottoms shrink down into nothingness, followed by a weird twisting, and inflating feeling as your internal femineity completed itself.
